Manowar show on the opening night of Kaliakra Rock Festival 2008 in the Bulgarian "rock capital" Kavarna lasted for five hours and one minute, setting the new world record for the longest heavy metal concert and breaking the record which they themselves set in 2007 at the same festival.

Scott Columbus left Manowar between "Kings of Metal" and "The Triumph of Steel" to care for his ill son. He rejoined for 1996's "Louder than Hell" along with new guitarist Karl Logan.

When the band "inked" a deal with Capitol Records in 1981, the contract was signed in their own blood to mark the occasion.

According to the band's official biography, Scott Columbus was such a ferocious drummer in his prime that normal drumsets would shatter by the end of a gig. This lead to the use of custom, stainless steel drumsets to avoid costly replacements for every show.

In the 1970s Joey DeMaio was a bass tech for Black Sabbath and played with David Feinstein in David Feinstein's Thunder.

Although the band has never been a mainstream commercial success, it has a strong cult following. These dedicated fans are known and referred to by the band as "Manowarriors" or "Immortals".

Drummer Scott Columbus joined the band, after a female fan introduced him to them, when she saw him striking the hot iron in the metallurgy he was working.

Manowar were once in the Guinness Book of World Records during the 80s as being the world's loudest band, with the vocalist singing at a record-breaking decibel level of 136.
